We don't see if you defined b and if you did, we don't see how you did it.

Its hard to impossible to debug a picture.

If possible please post the worksheet.

In Mathcad Prime define partial derivatives for the subsequent genfit using is not necessary. See attach.

Hi Saru.

Although the Viktor answer seems to me very correct, the error message in your function is just because b it's wrong: it could be a[1 instead.

Best regards.
